Sakai / uPortal / JSR-286 BOF

Charles Severance

Questions

• What do people want?• Who wants this so badly to work on it?

Easier Questions• How many would tolerate iFrames in the portal?

Or would you just keep Sakai as a bookmark which pops up in a new window?

• How many would use RSS do give a Dashboard view?

• How many simply want “all of Sakai under a tab”?• How many want Sakai Tools as placeable

channels?• How many want Tools contextualized in classes

as placeable channels.

Sakai WSRP

• Alpha quality consumer from Daresbury• Alpha quality producer from SunGard

– Sakai has a “sakai.fragment” - indicates body only response, and delegated URLs

– Not all tools - velocity tools work best– CSS is still Sakai’s CSS– Provisioning is weak - must look at Sakai

tool placement GUIDs and construct handles

Portlet = Placement

Sakai WSRP - Going Forward

• Waited 1 year for community resource to step forward

• UNISA will experiment with provisioning and productionizing WSRP with a simple scope.

• Still want to do a replacement for Sakai’s internal Aggregator which is available at a well-known handle “/gallery”

WSRP Challenges

• Getting CSS/Javascipt right - solve by putting Sakai CSS/Javascript into the portal HEAD

• Eliminating iframes and working through issues when we do back/refresh differently

• Performance re-tuning

Sakai Data Interoperability

... interoperability and data portability are key elements...

Sakai and RSS

• Sakai will likely add a number of RSS feeds for sites, tools, etc

• User-contextualized• This can allow Sakai to be integrated

into a wide range of applications including portals, browsers and desktop apps

Going Forward

• We will use the Sakai Portal list for the UNISA development discussions

• We will see where this goes - The community will lead here

• UNISA will blaze a trail connecting uPortal and Sakai - but the work will not be done– UNISA priority is to solve UNISA problems

• Others will have to continue to evolve the work.• Lets keep an open mind to HiJacking the

WSRP4J project in a branch
